EMBOSSlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 554,053, dated February 4, 1896. Application filed March 28, 1895. Serial No. 543,449. (No model.)-

To all whom, it may concern:

Be it known that I, MonrroN E. OoNvERsE, a citizen of the United States, residing at the town of \Vinchendon, State of Massachusetts, have invented a new and useful Improvement in Embossing-Machines, of which the following is a specification.

This invention relates to wood-embossing machines, and particularly to machines for embossing endless bands or hoops for drums and like articles; and it consists in the construction and novel arrangement of parts, as hereinafter specified, and particularly pointed out in the appended claims.

The object of my invention is to provide a machine upon which a number of endless bands or hoops may be placed for embossing and easily removed after the work shall have been done.

In the accompanying drawings, Figure l is aside elevation of an embossing-machine embodying my invention. Fig. 2 is a front elevation thereof, and Fig. 3 is a section through the line 3 3 of Fig. 1.

Referring by letter to the drawings, A designates the side frames of the machine, secured together by means of tie-rods a, and A is a forwardly-projecting or overhanging arm secured to the upper portion of the side frames.

A is a die-support-in g mandrel. This mandrel, at its inner end, has a loose bearing in a hanger a, and it rotates against antifrictionrollers a pivoted in cagings secured to the arm A. An arm a depends from the arm A, and has at its end a roller a which bears against the lower side of the mandrel A and serves to support the same. The mandrel A is preferably tubular, so that a torch may be inserted for heating the dies.

The embossing-dies B are annular and are removably yet tightly fitted on the mandrel. I have shown but two dies; but it is obvious that a greater number may be employed if desired.

B is the feed-roller upon which the bands or hoops b are placed for embossing. The feed-roller extends forward of the machine beneath the mandrel and is mounted on a shaft B which has bearings in travelers 6,

blocks 0.

per portion of the screws O and bevel-gears O on transverse shafts G which are rotated through the medium of a hand-wheel C The blocks or nuts O are vertically movable in the end frames, but are held from rotary motion by any suitable means.

D is a cam-shaft, having cams d at its ends, which engage against the lower ends of the When the cam-shaft is rocked by means of a hand-lever d, the cams will operate to raise the feed-roller and the bands thereon against the dies or to lower the same.

D designates guide-fingers for the bands or hoops. These fingers conform substantially -to the cylindric feed-roller and are adjustably mounted on a rod (Z extended from a plate 61 which is adjustably secured to the front traveler b by means of set-screws extendedthrough arc-shaped slots in the plate.

It will be seen that the fingers are adj ustable longitudinally of the feed-roller and also circumferentially thereof, so that the ends may be regulated with relation to the dies.

Rotary motion is imparted to the feed-roller through the medium of the band-wheel E, the power-shaft E, the worm-wheel thereon, and the worm-wheel e mounted on the lower end of a vertical shaft e The shaft e has a spline connection with a bevel-gear 6 so that there may be a vertical movement of the shaft relatively to the gear e and this gear e meshes with a bevel-wheel e, mounted on the feed roller shaft B The band-wheel E is loosely connected to its shaft E, so that said wheel may be in constant rotation without imparting motion to the machine. The machine may be placed in operative connection with the band-wheel by means of a clutch F, operated by a clutchlever f.

F is a screw extended through a tapped opening in the arm A for the purpose of limitin g the upward movement of the feed-roller.

From the above description the operation of the machine is quite obvious and need not be further described.

Having described my im'ention, What I claim is 1. In an embossing-machine, the combina tion with the frame, of the vertically-adjustable feed-roller having its outer end free, the guide-fingers adjustable longitudinally and circumferentially of said feedroller, the overhanging arm, the tubular die-mandrel supported thereby and the rollers bearing against the upper side of said mandrel substantially as specified.

2. 111 a machine for embossinghoops or endless bands, the combination with a frame, of the overhanging arm, the rotary mandrel supported thereby, the supporting-roller engaging the under side of the outer end of said mandrel, the rotary feed-roller, screw mechanism for vertically adjusting said roller, and cam mechanism for raising and lowering said roller substantially as specified.

3. A machine for embossing endless bands, comprising a frame, an arm extended therefrom, a die-supporting mandrel having a bearing in a hanger extended from the arm, autifriction-rollers engaging the rear end of the mandrel, antifriction-rollers engaging with the outer end of said mandrel, embossing-dies removably secured on the mandrel, a feedroller below the mandrel, the adjustable guide-fingers in connection with the feedroller and mechanism for operating the feedroller, substantially as specified.
